Question about Mitsubishi WS-55809 55" Rear Projection Television
Our 5 year old mitsubishi WS-55809 warranty expired last month! We just started experiencing a "bowed", distorted picture, which is worse around the edges of the screen than in the middle. Words split into multiple colors - red/green/blue. Same problem for DVD's. It fixes itself sometime, but not for long. The TV cost about $2,500, and the repair estimate is between $400 and $550. Other internet users have said this is a recurring problem. Is it worth fixing?
My TV is doing the same thing. Is it fixable? Is it something I can fix?

We took the back off a few weeks ago. Ran a multimeter over the the fuses. http://www.techlore.com/forum/thread/17103/Mitsubishi-WS-55809-Problems/?replyTo=16564#reply
They tested good. Pushed around on the heat sink. Whala, a real picture!! This worked for a few weeks. Then, back to the same old. So I took the back off again. Pushed on the heat sink (with a board of course) and we are back to a wonderful picture! Looks like we need to resolder the heat sink or convergence chips.
There are some pics towards the bottom of the thread listed below.

I've had the bow tie problem for about 9 months on my Mits 55809. For the first couple months it progressively took longer to go away upon startup, but since then has not got worse. The last couple months I've been tapping the top of the cabinet in the middle to make it go away and since then the condition has become less frequent with no ill effects to convergence.

You need to resolder the convergence chips. This is a very common issue with this line of TVs.
Hometheaterspot.com's Mitsubishi forum has detailed posts on how to fix this. Just serach for "55809 convergence" and you should find the info you need.
